Answer:
-5(t+3)(t-6)
Step-by-step explanation:
-5²+15+90
= -5(t²-3t-18)
= -5(t+3)(t-6)
Irrational because it keeps going on and on but doesn’t repeat
Answer: False
Step-by-step explanation:
The first thing we must do in this case is to rewrite the equation correctly:
T = 2 * pi * root (l / 32)
From here, we clear l:
T / (2 * pi) = root (l / 32)
l / 32 = (T / (2 * pi)) ^ 2
l = 32 * (T / (2 * pi)) ^ 2
Substituting values:
l = 32 * (1.57 / (2 * 3.14)) ^ 2
l = 2 feet
Answer:
the length is:
l = 2 feet
<span>The question is tricky. But any way the longest side of a right triangle is always the hypotenuse. So we know the hypotenuse if 15 cm.
Now, consider the Pythagorean theorem:
a^2 + b^2 = h^2, where a and b are the sides of a right triangle and h is the hypotenuse.
We know one side is 12cm and the hypotenuse is 15 cm, so:
12^2 + b^2 = 15^2, or </span><span>1</span><span>44 + b^2 = 225
subtract 144 from either side to get
b^2 = 225 - 144 = 81
now take the square root of either side to get
b = 9
The third side is 9 cm</span>
